Uh ~~ This attraction is really a bit boring. Before I went, the tour guide said that there was not necessarily an earthquake display every day. If you encounter a bridge overhaul, there is no, and there is also time requirements. Because South Africa is a country without earthquakes, so get a local earthquake bridge to feel it. We just caught up, but there was no shock. I feel that the deafening music next to it also brought a little vibration of the eardrum!
